VACUUM BOX (Electric Pump Generated)

The vacuum is generated by the use of an electric vacuum pump and external compressor. The vacuum boxes are rated to either 20 inch Hg (10psi/0,7bar) or 10 inch Hg (5psi/0.37bar) depending on usage.

The vacuum boxes have calibrated pressure relief valves fitted as standard. Also the boxes cannot be damaged by drawing too great a vacuum.
